What does the abbreviation "hs" signify for medication administration?

The abbreviation "hs" stands for "hora somni," which is a Latin term meaning "at bedtime." This notation is commonly used in medical contexts to indicate that a medication should be taken just before the patient goes to sleep. When medications are prescribed to be taken at bedtime, it is often for reasons such as promoting sleep, managing nighttime symptoms, or ensuring that the medication's effects will be active during the night. It is essential for caregivers and medication aides to understand this abbreviation to accurately follow medication administration schedules and to ensure optimal care for the patients they serve.
